Claims. (Cl. 261-65) The invention relates to a device for supplying a highly mixed and vapourized quantity of a special liquid mixture from a container to the intake manifold of an internal combustion engine so that the final mixture passing to the engine will eifect the better operation of the engine with increased mileage per gallon of fuel, better lubrication of the internal parts of the engine, minimize knocking and obviate to a great extent carbonization and burning of cylinders and valves.

A further object is to provide a self contained unit for the above purpose which can be easily and quickly mounted in operating position by placing a part of it between the detached connecting flanges of the engine carburetor and intake manifold and then reconnecting the flanges by the usual bolts supplied for the purpose, the tightened bolts passing through said part and serving to effectively clamp my device in a selected operating position.

A further object is to provide a unit which can be easily and cheaply manufactured and assembled and which serves to very thoroughly mix and vapourize the passing, special fuel used and to direct such highly vapourized mixture into the firing mixture passing from the carburetor to the manifold.

A further object is to provide the device with internal valves held normally seated by adjustable springs and designed to open automatically at a selected time and under the influence of the suction of the engine.

A further object is to provide the unit with rotary mixers rotated by the passing fuel. to break up and vapourize such fuel.

A further and more detailed object is to provide a unit embodying a tank to contain the special liquid mixture, an encased wick to feed the mixture from the tank to a vapourizing and mixing block supplied and to provide plates for insertion and mounting between the existing carburetor and intake manifold flanges, said plates rigidly supporting the block and being provided with passages leading from the base of the block to the existing passage for the usual firing mixture passing from the carburetor to the manifold.

A further object is to supply the plates with registering holes for registration with the existing outlets from the carburetor and intakes to the manifold and to supply circular slots surrounding said holes and communicating with the aforesaid passages in the plates and to provide the slots with comparatively narrow outlets opening to the areas through which the firing charge passes from carburetor to manifold.

With the above more important and other minor ob,

jects in view, which will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter described, reference being had to the accompanying drawings, in which:

in the drawings like characters of reference indicate corresponding parts in the several figures.

The device is a unit which can be easily and quickly mounted in operating position by simply undoing the customary bolts 1 which corniect the existing. base flange 2 of a carburetor 3 to the existing head flange 4 of the intake manifold 5 of an internal combustion engine and then inserting the mating, upper and lower plates 6 and '7 of the unit, between the detached flanges and subsequently inserting the bolts and tightening them up.

As carburetors and intake manifolds are well known, no further description of them is considered necessary.

The plates 6 and 7 are both of the same shape, as shown in Figs. 1 and 2'and both have a body portion A to become entered between the flanges 2 and 4 and a laterally extending portion B for supporting the block later described. The body parts A of the plates are supplied with registering holes A to receive the bolts 1 subsequent to the insertion of the plates and obviously upon the inserted bolts being tightened up the plates become securely fastened together and their extensions become very rigidly supported. Both plates are supplied with similar openings 8 and 9 which register with the existing openings through which the usual firing mixture passes from the carburetor to the manifold.

I might mention here, that with eight cylinder engines, there are usually two passages for the firing mixture in passing from the carburetor to the intake manifold, and such is the reasonthat the two holes 8 and 9 are herein shown. Engines with less cylinders might require only one set of registering holes in the plates to register with the existing holes in the connecting flanges 2 and 4.

The block, generally indicated by the reference letter C, is herein shown as cylindrical and it is in the form of a solid piece of metal drilled and plugged to give the required passages, holes and ducts required. The lower end of the block is shouldered to seat in a hole 10 cut in the upper plate 6 and the block is securely held in place into a central, vertical, drilled passage 13 extending through the block. The upper end of the block is also shouldered to receive the circular flange 14 of the cover 15 and the arrangement is such that there is an internal chamber I 6reseryed between the top of the cover and theto'p en'd offlthe block, A central fastening bolt- 17,

isprovidedto tightly seatthecover, the bolt being screw threadedinto the upper end of the passage 13 and being suppliedwith a finger piece 17 and with a circumscribing flange 17' engageable with the top of the cover.

Associated with the block is a relatively small tank D' for a fluid mixture and the fluid is highly mixed and vapourized in passage from the tank to the openings 8 and 9.j and by way of the block. I have found that a fluid mixture of lubricating oil and castor oil very effectively serves my purpose, the vapourized lubricating oillubri'cating internalpart's of the engine and the vapourized castor oil very efiectively preventing carbonizin g and burning of internal engine parts such as-cylinder walls, and valves.

The tank is substantially rectangular and is supplied with a filling plug 18 and contains a curved pipe 19 secured to an end wall of the tank and which pipe curves downwardly and contains a-wick 20, the lower end of which is exposed within the tank as indicated at 20.

The flange of the cover is fitted with a relatively short nipple 21 (see Fig. 13) and the nipple opens to the chamber 16. A stiff pipe or tube 22, of desirable length, connects the tank to the block, suitable couplings 23 and 23 being supplied to screw to the nipple and to the pipe 19. Actually the pipe 22 can be selected in length and shape to best accommodate the unit to the particular engine without interference with existing engine parts.

The wick, already mentioned, is threaded through the pipe 22 and the nipple 21 and enters the chamber 16 and has its entered end coiled over the top of the block as shown. A fine wire screen 24 is placed over the coiled end of the Wick and atmospheric air is admitted to the chamber through a plurality of similar holes 15' drilled through the cover. Obviously the wick will liberate oil to mix with the air admitted to the chamber.

Two similar, vertical, side passages 25 and 26 (see Fig. 5) are drilled in the block and such have their upper ends communicating with the chamber and their lower ends'communicating with similar, internal, hori zontal ports 27 and 28 also bored in the lower part of the block and which ports communicate with similar, short, vertical ducts 29 and 30 drilled in the block (see Fig. 4) and provided at their upper ends with similar valve seats 31 formed in the lower ends of similar vertical passages drilled in the block and indicated by the reference numerals 32. These passages, each, have their upper end closed by screw plugs 33 and 34 which can be adjusted and locked in adjusted position to adjust the pressure of underlying, coiled'springs 35' which have their lower ends resting on ball valves 35, in turn seated on the valve seats 31. The ball valves are of such diameter that a clearance space is reserved between the ball and the containing wall of the passage 32.

Similar, angularly disposed, horizontal holes are drilled in' the block, to provide further, similar ports 36 and 37 leading from the valve chambers 38 to another pair of vertical passages 39 and 40 (see Fig. 3) which are drilled in the block and have their upper ends closed by screw plugs 41 and their lower ends tapered at 42 to communicate with lower outlet ports 43 opening to similar, diverging, slotted passages 44 and 45 supplied in the underside of theplate 6. Actually the latter passages are closed by the underlying plate 7.

The passages39 and 40 provide cylinders which rotatably receive rotary mixers 46 and 47 which are circular in cross section. The two mixers are identical in construction. Each mixer has its upper end circumferentially slotted to provide a continuous, horizontal passage 48 and its lower end tapered to seat on the tapered lower end 42; of the associated passage 39 or 40 as the case may be and the arrangement is such that the passaga' ts'cominusiaae continuously with the entry ports 36 and '37 when the mixers are seated and which is the position they always maintain. The face of each mixer is provided with a plurality of similar, downwardly spiralling, spaced ducts 49 which have their upper ends opening to the passage 43 and their lower ends communicating with similar, ingoing ports 50 (see Fig. 12) drilled in the lower end of the mixer and communicating with a central, vertical passage 51 drilled in the mixer and which passage connects, in the seated position of the mixer, with the lower outlet port-43. Inotherwords, any vapour I entering the passages 48 passes downwardly through the ducts 49 and is then directed to the diverging passages 44 and 45 in the underside of the plate 6, and which lead to the openings 8 and 9.

In the underside of the upper plate 6, I cut similar, circular slots 52 and53 which surround the openings 8 i and 9 (see Fig. 7) and each slot has a continuous, re-

stricted, or narrow side outlet 54 which communicates with the opening. 8 or 9 as the case may be, it being understood thattheunderlying plate 7 closes the open side ofthe slots andoutlets 54.

The above completes the description of the unit and the manner it is secured in operating position on the engine. Y

When in operation, the suction of the engine causes a flow from the tank to the openings 8 and 9. The vapour arising from the wick initially mixes with atmospheric air admitted to the chamber 16 through the openings 15' in thecover 15. This mixture passes down through the passages 25fand 26. to the ducts 27 and 28. At these points, the suction of the-engine has unseated the ball valves 35 so that the vapour passes upwardly to the ports 36 and 37 and to the circular passages 48. From there themixture goes down through the spiralling ducts 49 to the central passages Slandis liberated to the diverging passages l landfis which direct it tothe slots 52 and 53 Where it discharges into the passing firing mixture through the narrow outlets 54.

In passage from the tank to the points of admission to the firing mixture, thespecial mixture supplied by the tank is very eifectively mixed and highly vapourized. The valves can be set so that they will remain closed for a desired period of time during the starting of the engine and on such account there is no change made in the firing mixture passing to the engine. This results in easy starting, in the usual way. Subsequently as the suction of the engine increases, the valves open and allow my highly vapourized mixture to enter the passing firing mixture and to become intimately intermixed therewith; Obviously thevalves. will close when the engine stops operating.

It will be. obvious that the mixers will rotate under the pressureof the vapour passing downwardly through the spiralling ducts49..and so operate to break up and vapourige the passing. mixture.
